The Navtech Systems GPS LNA (NTS-DP0) amplifies low level signals from passive or low gain antennas. Using a combined low noise amplifier and power by-pass circuitry, the GPS LNA antenna will amplify GPS signals to a receiver connected to the output. Antenna power, supplied by the GPS receiver, is by-passed to the antenna to enable active antennas to be used as the primary signal source on any GPS installation.
By simply inserting the GPS LNA in the antenna feeder cable, using standard TNC connectors, the GPS signal is correctly terminated and amplified to the receiver.
